A novel ECC protocol for key exchanging in non-PKI networks

In this paper we describe a novel ECC protocol for public key cryptosystem in non-PKI environment. The proposed protocol is designed to avoid the expensive infrastructure of PKI and the key escrow problem of the id-based cryptosystem. We based on elliptic curve discrete logarithm problem to build a practice key exchanging protocol in short key, low power, and small storage requirements of the communicate application with constrain devices. The protocol guarantees the private key generated by the legal user instead of the third party who may have the chance to conspire with an adversary.
